(closed to new enrollment)
Fibromyalgia (FMS) is a common chronic pain syndrome that is disabling to patients and costly to the society. FMS is devastating to the individual’s quality of life and family members. Despite intense research, what causes fibromyalgia is poorly understood and no single therapy is found to be beneficial to all patients.
The primary goal of this study is to collect pilot data in order to evaluate the effect of low dose blood pressure medication, propranolol, on fibromyalgia symptoms using two different doses. This study is funded by the Department of Anesthesiology at the University of Utah. All participants will be screened for eligibility and those who complete the entire study will be compensated for their time.
Participants will attend three separate study visits. During the initial visit, participants will undergo a tender point analysis, fill out several questionnaires assessing symptoms related to quality of life and FMS, have an electrocardiogram, and be shown how to take their blood pressure with the device provided. At the 2 nd visit, participants will return their blood pressure log and received either 10 mg, 20 mg of propranolol or placebo medication and be asked to take it twice a day for two weeks. They will continue to monitor their blood pressure for the next two week and will receive a new blood pressure log at this visit. At the 3 rd visit, participants will fill out the same questionnaires they completed at the initial visit, have another electrocardiogram and return the blood pressure device they received at the beginning of the study.
